Problem: The IRS has rejected your tax return extension - not eFile.com - because the primary SSN on this return can not be the same as the primary SSN on another already filed and accepted IRS tax return extension.
Solution: Let us help you turn this into an IRS acceptance. Sign into your eFile.com account: https://mytaxes.efile.com/1040/SignIn/, and click Name and Address on the left side menu. Check the primary SSN and make necessary corrections of updating the primary SSN. Save the changes, click Continue and follow the screen instruction to re-efile your IRS federal tax return extension for free. You can do this as often as it takes to get accepted. However, should you have entered your primary SSN correctly and you keep getting rejected for any reasons, PRINT your extension and MAIL it in on time here: https://www.efile.com/where-to-mail-tax-return-form-irs-mailing-address-for-refund/
After that, contact the IRS at 1-800-829-1040 discuss your tax return extension in more detail or file a tax return first.
